WSDM (pronounced "wisdom") is one of the premier conferences on web-inspired research involving search and data mining. The 12th ACM International WSDM Conference will take place in Melbourne, Australia during Feb. 11-15, 2019.

WSDM is a highly selective conference that includes invited talks, as well as refereed full papers. WSDM publishes original, high-quality papers related to search and data mining on the Web and the Social Web, with an emphasis on practical yet principled novel models of search and data mining, algorithm design and analysis, economic implications, and in-depth experimental analysis of accuracy and performance.
Original papers emphasizing novel algorithmic approaches are particularly encouraged. Application-oriented papers that make innovative technical contributions to research are welcome. Visionary papers on new and emerging topics are also welcome.

## Submission Guidelines

### Originality of Submissions
Submissions must represent new and original work. Concurrent submissions are not allowed. Papers that have been published in or accepted to any peer-reviewed journal or conference/workshop with published proceedings, or that are currently under review, or that will be submitted to other meetings or publications while under review may not be submitted to WSDM 2019. However, submissions that are available online and/or have been previously presented orally or as posters in venues with no formal proceedings, are allowed. Note that if available online (e.g., via arXiv) and not anonymous, their titles and abstract must be sufficiently different from the WSDM submission in order to limit the risk that a direct search breaks the double blind reviewing procedure. Additionally, the ACM has a strict policy against plagiarism and self-plagiarism. All prior work must be appropriately cited.

### Submissions
Papers must be submitted in PDF according to the new ACM format published in ACM guidelines, selecting the generic "sigconf" sample. Submissions should not exceed eight pages including any diagrams or appendices, plus up to one additional page of references. The PDF files must have all non-standard fonts embedded. Submissions must be self-contained and in English. After uploading your submission, please verify the copy stored on the easychair site. Submissions that do not follow these guidelines, or do not view or print properly, may be rejected without review.

PDF files submitted to WSDM 2019 must be prepared as double-blind: the submitted document should not include author information and should not include citations or discussion of related work that would make the authorship apparent. Note however, that it is acceptable to explicitly refer in the paper to the companies or organizations that provided datasets, hosted experiments or deployed solutions. In other words, instead of stating for instance that an experiment “was conducted on the logs of a major search engine”, the authors should refer to the search engine by name. The reviewers will be informed that it does not necessarily imply that the authors are currently affiliated with the mentioned organization. To support identification of reviewers with conflicts of interest, the full author list must be specified at submission time. Only in exceptional cases will the PC Chairs grant permission for modifications to be made to the author list of a paper once it has been submitted and accepted.

### Review Process
Each paper will be reviewed by at least three PC members and a senior PC member. The acceptance decisions will take into account paper novelty, technical depth, elegance, practical or theoretic impact, and presentation. WSDM 2019 will use a combination of single-blind reviewing and double-blind reviewing. The papers will be double-blind to regular PC members, but the metadata (including authorship) of the papers will be available to SPC to check for undisclosed
conflicts of interest and to help assure the integrity of the review process. Please contact the PC chairs at the address below for any questions on the submission or review process.

### Reproducibility
The algorithms, resources and methods used within a paper should be described as completely as possible. Authors may reference supplementary material, including detailed descriptions, test datasets or code. However, this information is not part of the submission proper, and will be read only at the discretion of the reviewers. Wherever appropriate, the authors are encouraged to use publicly available test collections and state-of-the-art baselines. Please consider sharing your intermediate/final experimental results and code with the research community.

### Publication and Presentation
All accepted papers will be published in the ACM Digital Library. For every paper there must be a registered author to present it in person at WSDM 2019. At the conference, all the papers will be allocated a slot at the interactive poster session to encourage discussion. Additionally, selected papers will be presented during the plenary oral sessions as either long or short talks. Other presentation opportunities may also be provided upon acceptance, e.g. a brief video presentation.

Authors should note that the official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work.


## Conflict of Interest (COI) Policy

All authors must declare conflicts of interest. ​​​

### What Consitutes a Conflict of Interest (COI)
You must declare a reviewer/author as a conflict of interest when the following associations exist:
• employment at the same institution or company, regardless of geography/location
• candidate for employment at the same institution or company
• received an honorarium, stipend, or grant from the institution or company within the last 12 months (except where of a modest nature, such as reimbursement of seminar expenses, honorarium for examination of a thesis, and so on).
• employment at the same institution or company in the last 12 months
• co-author on book or paper in the last 24 months
• co-principal investigator on a funded grant or research proposal in the last 24 months
• actively working on any project together
• family relationship
• close personal relationship
• graduate advisee/advisor relationship, regardless of time elapsed since graduation
• deep personal animosity

In general, we expect authors, PC, the organizing committee, and other volunteers to adhere to ACM’s Conflict of Interest Policy as well as the ACM’s Code of Ethics and Professional Conduct.

### Violations of Originality, Dual Submission or Conflicts of Interest
Papers that are submitted which do not meet the length, formatting or originality requirements or are dually submitted to two venues (including papers with significant overlap) are subject to desk rejection without review. At the discretion of the PC Chairs and Steering Committee, egregious violations (including plagiarism) may lead to additional penalties such as a temporary or permanent ban from the venue and sponsoring SIGs venues. Likewise, failure of an author to disclose all COIs or of a referee providing a review on a paper for which they have an undisclosed COI, may lead to similar penalties. You are encouraged to contact the PC Chairs if you have questions as to the originality conditions, dual submission, or conflicts of interest policy.
